A scatter diagram is used to plot the relationship between two continuous variables, in this case, the hours studied (independent variable) and the exam score (dependent variable). A histogram is used to plot the distribution of a single continuous variable, while a bar chart is used for categorical variables. A pie chart is used to show the proportion of different categories in a dataset.
